IMPROVEMENT IN TURBlNE WATER-WHEELS.

Specification forming part of Letters Patent No. 158,147, dated December22,1874; application filed December 2, 1873.

To all whom it may concern.-

Be it known that I, SAMUEL T. TEAcEoUr, of Troy, Rensselaer county, NewYork, have invented an Improvement in Turbine Vater- Vheels, of whichthe following is a specification:

My invention relates to that class of turbine-wheels in which a seriesof gates are operated by means of a cam-ring; and my invention consistsin constructing the casing'A so as to atibrd a bearing for the ring D',which operates directly upon the independent gates B, as shown in thesectional elevation, Figure l, side view, Fig. 2, and plan view, Fig. 8,of the accompanying drawing. `Each gate B slides between vertical guidesb on the outer casing, and the ring Dl rests in a recess, D, on a ledgeabove the passages a, and is confined to its place by an annular plate,G, and on the inner periphery of this ring are teeth, into which gears apinion, e, on a vertical shaft, h, which passes through the plate G, andis furnished with a suitable hand-wheel, t'. In the outer periphery ofthe ring D are two grooves, ff, for receiving antifriction rollers onpins n, projecting from the gates B, the pins of one-half of the gatesbeing adapted to one groove, and those of the other half of the gates toother grooves. One portion of each groove is lower than the other, andthe Y two portions communicate with each other through an inclinedcontinuation, m, as shown in Fig. 2, where the gatesB, B, B, and Bf areunder the control of the groove f', so that on turning the ring D in thedirection of the arrow the gate B will descend and close its passagesimultaneously with the descent of a corresponding gate, which issituated on the opposite side of the wheel, and is controlled by thegroove f. By continuing the movement of the ring another pair of gateswill be closed, and so on, so that by the turning of the ring as manygates may be opened and as many gates closed as the supply of water maysuggest.

I do not claim that the improved wheel above described involves any newprinciple or mode of operation, my invention being restricted to thespecial construction, whereby simplicity, cheapness, and durability areobtained, such construction consisting in adaptsaid gates, as set forth.

In testimony whereofl have signed my naine to this specification in thepresence of two subscribing witnesses.

SAMUEL T. TEACHOUT.
